Dunne told his club's official website: "Retiring from international football has been an extremely difficult decision for me to make."

Dunne is currently on tour in Ireland with the QPR squad as they prepare for a return to the Premier League. The west London side have friendly matches against Shamrock Rovers on Saturday and Athlone Town on Tuesday.

He continued: "I have represented Ireland since I was 15 years of age, and have thoroughly enjoyed all the highs and lows that have come with playing for my country.

"I will continue to support the team as they embark upon their new campaign under Martin O'Neill, and have every faith that they will qualify for France 2016.

"I'd like to thank everyone I worked alongside during my time with Ireland, from managers, to players, to backroom staff. I have so many great memories that will stay with me forever."

Republic boss O'Neill said: "Richard has been a remarkable player for both club and country. I had the pleasure of working with him at Aston Villa, where he had a big influence on the field.

"He has consistently given 100 percent every time he has been called on by his country also. I wish him all the best in his club career."

Football Association of Ireland chief John Delaney said: "Richard has been a tremendous servant to his country and is truly a player for Ireland to be proud of.

"I will never forget his performance in Moscow, which was instrumental in winning us qualification for Euro 2012. Richard and his family, particularly his parents Dick and Phyllis, will always be welcome guests in Aviva Stadium.

"On behalf of the Association, I would like to wish him and his family the very best for the future."
